# Functions

# new


Signature	`cp.websocket.http.new(url, callback) -> object`
Type	Function
Description	Creates a new websocket connection via a serial connection.
Parameters	url - The URL path to the websocket server. callback - A function that's triggered by websocket actions.
Returns	The `cp.websocket` object
Notes	The callback should accept two parameters. The first parameter is a `cp.websocket.event` value. The second parameter is a `string` with the received message or an error message. Given a path '/mysock' and a port of 8000, the websocket URL is as follows: `ws://localhost:8000/mysock` `wss://localhost:8000/mysock` (if SSL enabled)
Examples	None

# Methods

# close


Signature	`cp.websocket.http:close() -> object`
Type	Method
Description	Closes a websocket connection.
Parameters	None
Returns	The `cp.websocket.serial` object
Notes	The `status` may be either `closing` or `closed` after calling this method. To be notified the close has completed, listen for the `cp.websocket.event.closed` event in the callback.
Examples	None
Source	src/extensions/cp/websocket/http.lua line 175

# isOpen


Signature	`cp.websocket.http:isOpen() -> boolean`
Type	Method
Description	Gets whether or not the HTTP websocket is fully open.
Parameters	None
Returns	`true` if open, otherwise `false`.
Notes	None
Examples	None
Source	src/extensions/cp/websocket/http.lua line 133

# open


Signature	`cp.websocket.http:open() -> cp.websocket.status`
Type	Method
Description	Attempts to open a websocket connection with the configured HTTP connection.
Parameters	None

# send


Signature	`cp.websocket.http:send(message[, isData]) -> object`
Type	Method
Description	Sends a message to the websocket client.
Parameters	message - A string containing the message to send. isData - An optional boolean that sends the message as binary data (defaults to true).
Returns	The `cp.websocket.serial` object
Notes	Forcing a text representation by setting isData to `false` may alter the data if it contains invalid UTF8 character sequences (the default string behavior is to make sure everything is "printable" by converting invalid sequences into the Unicode Invalid Character sequence).
